What are some unusual toads in the toad family?

  Some toads are really unusual. The European common toad can be found across three continents, including Africa. They secrete a toxin that makes them unpleasant to predators. They sometimes stand up on their toes in a defensive posture. But they have no teeth, and aside from tasting bad and attempting to look menacing, these gentle creatures have no other defense. The Asian horned toad has fleshy horns projecting over its eyes that make it look exactly like a dead leaf, lying on the ground. The Asian tree toad has discs on its fingers and toes and horizontal pupils while the natter jack toads have special sounds that can be heard over several kilometres!
